The kettle shape is designed to distribute heat evenly, and a grill reflects heat off the curved lid back onto the food and restricts oxygen flow through the coals.
Kettle grills outperformed the other grills in cooking, ease of assembly, and user-friendly details.
Kettle grills make pretty good smokers. The main disadvantage is that you have to open the cover to add more charcoal and wood or to check your meat, which lets out heat and precious smoke. So, to make sure you do that as infrequently as possible.
Includes an air vent in the Lid and a temperature gauge.
